My ds is 3 in August and has always slept well. He dropped his daytime sleep as he wasn't settling and has also learnt to open his bedroom door! Since then he has been difficult to get to bed in the evenings despite being v.tired. After many evenings of continually putting him back we seem to have cracked it. However, he is up every morning between 5-5.30am and although put back to bed will not stay there. We have blackout blinds and even blackout curtains over the top but he is still awake. I wouldn't mind if he had had enough sleep but he is sooo tired . He is falling asleep in the car/on the sofa/all over the place and is continually whining/crying/tired. He is also waking his 6 year old brother, so then both of them are grumpy - please help.
